2 CONNECTING THIRD PARTY OPTIONAL DEVICES10 Contents Confidential MOD (K)/Ver. 1.04 Attenuating the Sidetone1. Install a chip resistor in the position of R508.The volume level of the Sidetone can be reducedby installing a chip resistor, R508.z The transceiver whose serial number isbetween 607xxxxx and 609xxxxx:Attenuation ratio is calculated asR508/ 10kΩ. Recommended value is 1kΩ.Installing 1kOHM resistor, the Sidetonevolume is approximately 17dB attenuated.z The transceiver whose serial number is701xxxxx and after:Attenuation ratio is calculated asR508/ (8.2kΩ + R508). Recommended valueis 1kOHM.Installing 1kOHM resistor, the Sidetonevolume is approximately 17dB attenuated.2.2.3 Installing an Optional Board inthe TK-52101. Connect the Optional Board Connector PCB to theconnector of the TX-RX PCB (X57-6820-10).2. Peel off the backing from the tape on the rear surfaceof the QE-2 board and attach the cushion on thecentral part of upper inner wall of the chassis.3. Reinstall the cover and battery pack.2.2.4 Configuration using KPG-95DYou can write the ANI Board information to thetransceiver using KPG-95D after installing the ANI Board.Follow the procedure below.1. Run KPG-95D.You must read the data from the transceiver or usedata configured in the transceiver when adding theANI Board information to the current configurationdata. Refer to the Field Programming Reference forinstructions on how to read the configuration datafrom the transceiver.R508R508Insert it here.
